Perennial, shrub, tree.
Stem: bark often peeling distinctively.
Leaf: simple or 0, generally cauline, alternate, opposite ( whorled), evergreen or deciduous, often leathery, petioled or not; stipules 0.
Inflorescence: raceme, panicle, cyme, or flowers 1, terminal or axillary, generally bracted; pedicel often with 2 bractlets.
Flower: generally bisexual, generally radial, bell-shaped, cylindric, or urn-shaped; sepals generally (0)4–5, generally free; petals generally (0)4–5, free or fused; stamens 8–10, free, filaments rarely appendaged, anthers awned or not, dehiscing by pores or slits; nectary generally present at ovary base, generally disk-like; ovary superior or inferior, chambers generally 1–5, placentas axile or parietal, ovules 1–many per chamber, style 1, stigma head- to funnel-like or lobed.
Fruit: capsule, drupe, berry.
Seed: generally many, winged or not.
± 100 genera, 3000 species: generally worldwide except deserts; some cultivated, especially Arbutus, Arctostaphylos, Rhododendron, Vaccinium. [Kron et al. 2002 Bot Rev 68:335–423] Monophyletic only if Empetraceae included, as treated here. Ledum included in Rhododendron.
